This invention relates broadly to window ventiy One of the objects of the invention is to provide a ventilator unit of rectangular cross section having rigid end portions and an intermediate wire mesh or screen portion adapted to eifect the circulation of air therethrough in a tortuous path.

Another object of the invention is to provide a ventilator unit having a deector therein to control the currents of air passing therethrough and preclude the entry of rain.

Another object of the invention is to provide a ventilator comprising a plurality of like units adapted for assembly with each other in superposed relation.

Another object of the invention is to provide a baille formed from a finely-woven screen section or multiple layers of screen disposed to control the passage of air therethrough.

Another object of the invention is to provide a ventilator unit having a diagonal plate extended through the length thereof to serve as an air or rain deilector and to increase the rigidity of the screen structure.

Another object of the invention is to provide rigid sheet metal end sections for the ventilator units having telescopic sleeves thereon which are formed with inclined end walls to facilitate the ready insertion or removal of the units.

Another object is to construct a ventilator comprising an assembly of similar units having interengaging members therein disposed to facilitate the alignment of the units when arranged in superposed relation.

Other objects and advantages more or less ancillary to the foregoing and the manner in which all the various objects are realized will appear in the following description, which considered in connection with the accompanying drawings, sets forth the preferred embodiment of the invention.

Referring to the drawings:

Fig, 1 is an elevational view of a window illustrating a pair of the improved ventilator units in place therein;

Fig. 2 is a. transverse section through the window and ventilator illustrated in Fig. 1, the section being taken on the line 2-2 of Fig. l;

Fig. 3 is a front elevational view of one of the improved ventilator units;

Fig. 4 is a vertical sectionthrough an end portion and sleeve of the ventilator unit illustrated in Fig. 3, the section-being taken on the lined-'4 of Fig. 3;

Fig. 5 is a vertical section through the 'ventilator unit adjacentthe end portion thereof, the section being taken on the line 5-5'of Fig. 3;

.Fig.- 6 is a transverse section through Ia ventilator unit of almodied form, the section being taken through the central portion thereof; and

Fig. 'I -is anotherV modified form of a ventilator unit illustrating an alternate' type of baille, the baffle illustrated herein being forme-d of a section of fine mesh screen.

Referring rstzto Figs. l and 2, the ventilator comprises a plurality of rectangular screen units II) 'preferably formed of a-wiolthv substantially equal'to the thickness of the window sash II and of suitable length yfor assembly in window finen-k ings ofstandardwidth. The major portion of" the ventilator units are formed of screen, such for exampleas the mesh normally-used in the construction of fly screens. The screen is folded in tubular form ofv rectangular crosssection and provided with sheet metal end members or thimbles I2 soldered, welded, or otherwise afliied tothe screen. The end members I2 fare provided with telescopic sleeves I3 formed. with mitered parallel louter ends I4 to facilitate the removalof `the 'units by elevating one end thereof to a point which will accommodate the retraction of the ventilator unit over the stops I5 in the window frame. The angle Aof the mitered endsof the sleeves I3 is designed for. overlapped relation with stops I5 in the average installation. 'Ihe telescopic sleeves I3 further provide for the installation of the ventilator units in windows of various widths. The body M of the screen is preferably formed with a strip I'I of sheet metal or substantially imperforate material disposed in diagonal relation therein. Air passes through this form of ventilator by entry through a subjacent unit, through the bottom face I9 of the unit, and thence through the inner vertical wall 20 thereof.

Referring next to Figs. 2, 3 and 5, legs 2| are secured to the lower faces of the thimbles I2 adjacent the screen section M. The legs are ldisposed outwardly from the vertical center line of the units to facilitate the level mounting thereof on the inclined surface of the bottom member 22 of the window casing. The upper faces of the sleeves are provided with holes 23 for the reception of the leg-s 2| depending from the superjacent unit of the ventilator as assembled in a window frame. v

In the modiiied baille structure illustrated in Fig. 6, the upper wall of the screen is bent downwardly and inwardly to form a longitudinal V- section 24 which obviously will multiply the num- Iber of strands across the upper area of the unit and thus retard the circulation of air through Athe unit and arrest the passage of rain through that portion of the ventilator. This embodiment is primarily adapted for use as a base section of the assembly where the window sill I8 obstructs the lower portion thereof, and may be used in combination with the preferred structure illustrated in Fig. 5. n e

In the modiiication illustrated in Fig. 7, the intermediate screen section and the diagonal bale therein are folded from one piece of mesh, the baille portion 25 thereof being formed of a finely woven pattern capable of precluding the passage of rain or from a plurality of layers of screen disposed With the strands of the various layers in staggered relation to effectively reduce the interstitialarea.

Among `the many advantages'attending the improved ventilator are economy of manufacture, due to the simple construction and the use of cheap, easily procurable materials; emciency of operation, chiey due to the use of the total height for ventilation and the well designed 'and proven baille means; ease of insertion and removal resultingffrom the use of the mitered ends of the sleeves; and sales appeal resulting from the features mentioned above combined withnatural attractiveness and the ability to add' sections to give increased ventilation area.

Although the foregoing descriptionis neces sarily of a detailed character, in order that the invention may be completely set forth, it is to be understood that the specific terminology is not in-j tended tobe restrictive or conning, and that various rearrangements of parts and modifications of detail may be resorted to without departingA from the scope or spirit of theinvention as herein claimed.

I claim: l A

1. As an article of manufacture, a window ventilator of the type adapted to be inserted below a windowl sash comprising a wire' mesh tub'eof rectangular cross-section, 'sheet metal thimbles secured thereto, sheet metal sleeves `telescopically engaged with said thim-bles, and a baille insaid tube for the deflection of the air passing therethrough.

2. As an article of manufacture, a portable wind0 file of this patent:

dow ventilator comprising a rectangular tube formed of fly screen, baille means therein, imperforate end portions on said tube, sheet metal sleeves on said end portions, the outer ends of said sleeves being in oblique relation to the axis of said tube and in parallel relation with each other to facilitate the elevation of one end of the ventilator when mounted in a window.
